Rio Olympics: These Marketers' Ads Are the Most-Seen So Far

Based on 11 Million Smart TVs, These Spots Got the Most Real-World Play

As the medal counts get underway in earnest, it's also time to take stock of how the Olympics' TV advertising is playing out. And not every big spender is getting the same amount of eyeballs.

Halfway through the Olympics, 351 brands have run 667 unique TV ads a total of 7,867 times, 1,488 of them in primetime, according to data from iSpot.tv. That's spanning NBC and its NBC Universal siblings NBC Sports, USA Network, BRAVO, MSNBC and CNBC.

By analyzing ads appearing on the screens of 11 million smart TV sets, iSpot.tv estimates that NBCU has already delivered more 7.7 billion TV ad impressions in the U.S. The games are providing solid retention for advertisers too, with ads viewed to completion an average of 90% of the time and 97.4% of all ads getting viewed live or same day.

Of those TV ad impressions, auto makers can claim 1.128 billion, insurance marketers 518 million, movie studios 431.7 million and credit card companies 351 million. NBCU is giving its share of promo time to shows such as "Timeless," "This is Us" and "Sunday Night Football," each with trailers appearing on screens more 120 million times thus far.

Excluding show promos, no single ad has seen more action than this Visa Carpool ad, which has registered on TV screens 140.9 million times.

Though you may also be getting tired of this Chevy ad touting the Malibu, Camaro and Equinox, given the 120 million impressions it has registered in 7 days.

Here are the top five brands receiving the most screen time the first week of the Olympics:

No. 1. BMW, with an estimated spend of $18 million, has run 10 different creatives 113 times for 262 million TV ad impressions. The brand's future-themed ads have held viewers' attention, with a completion rate of 89%.
